       9. The liquid dispenser of  claim 8 , wherein the plate is located above an upper end of the outer guide wall, and a shape of a perimeter of an upper end of the outer guide wall corresponds to a shape of a perimeter of the plate. 
     
     
       10. The liquid dispenser of  claim 9 , wherein a diameter of the upper end of the outer guide wall is larger than a diameter of the plate. 
     
     
       11. The liquid dispenser of  claim 9 , wherein the tank further includes:
 a bottom plate defining a bottom of a space in which liquid is stored; and 
 a container support on which the bottom plate is mounted, wherein the wall of the tank extends upward from the container support and has a radius that decreases from a lower end toward an upper end. 
 
     
     
       12. The liquid dispenser of  claim 11 , wherein the wall of the tank includes a main wall extending from the container support and an upper wall positioned on an upper end of the main wall, wherein an inner tank wall is coupled to the upper wall and has a radius that increases from a lower end to an upper end, and wherein the outer guide wall has an outer inclined surface supported by the inner tank wall. 
     
     
       13. The liquid dispenser of  claim 12 , wherein the inner tank wall and a portion of the outer inclined surface contacting the inner tank wall have equal inclinations. 
     
     
       14. The liquid dispenser of  claim 12 , further including
 a first protruding plate extending radially inward into the tank from the upper wall and having a first length; and 
 a second protruding plate extending radially inward into the tank from the upper wall and having a second length longer than the first length, wherein the inner tank wall 
 connects the first protruding plate and the second protruding plate. 
 
     
     
       15. The liquid dispenser of  claim 14 , wherein the outer guide wall has an upper and lower portion, wherein the lower portion includes the outer inclined surface supported by the inner tank wall, wherein a step portion is formed on an outer surface of the outer guide wall between the upper and lower portions of the outer guide wall, wherein the step portion is placed on an inner end of the first protruding plate, and wherein the upper portion of the outer guide wall is inclined outward from the step portion to an upper end. 
     
     
       16. The liquid dispenser of  claim 15 , further including an extension extending from the upper wall and an outer end of the first protruding plate, wherein a bumper is provided on the extension, and wherein the upper portion of the outer guide wall is in contact with the bumper when the liquid guide is placed in the tank. 
     
     
       17. The liquid dispenser of  claim 16 , wherein a bottom surface of the bumper is provided on an upper surface of the first protruding plate, and an outer surface of the bumper is provided on an inner surface of the extension.
